Problems solved by technology

Because sweetfish has a countercurrent habit and is very active, the sweetfish compound feed requires good water stability. The traditionally processed sweetfish compound feed adopts hard pellets or extruded pellets. The manufacturing process does not pay attention to the research on processing technology. Only through the use of raw materials such as adhesives to improve the stability of feed in water, resulting in low digestion and utilization of feed, high N and P content in excreta, serious waste of feed and pollutio

Embodiment 1

[0028] Embodiment one: produce 1# fragrant fish compound feed

[0029] Take 100kg of raw materials to process 1# sweetfish compound feed as an example, the ratio of raw materials is (unit kg): white fish meal 8, imported red fish meal 42, shrimp bran 3, viscera powder 2, brewer’s yeast 3, gluten powder 4, soybean meal 6. Soy lecithin powder 2, seaweed powder 2, flour 19, corn gluten powder 4, fish oil 3, ayu premix 2.

[0030] Mix various raw materials (except flour, fish oil and sweetfish premix) until the coefficient of variation of mixing uniformity C.V. Add flour and sweetfish premix, spray fish oil while mixing, and mix until the coefficient of variation of mixing uniformity C.V. 100°C, the conditioning time is 2.5-3.0 minutes, optimize and adjust the single-screw extrusion extruder, the first section of the screw at the discharge port adopts a single-tooth notched screw, and install a section of the air outlet elbow in the main machine expansion chamber, after condition...

Embodiment 2

[0032] Embodiment two: produce 3#L sweetfish compound feed

[0033] Taking 100kg of raw materials to process 3#L sweetfish compound feed as an example, the ratio of raw materials is (in kg): white fish meal 5, imported red fish meal 40, shrimp bran 5, viscera powder 2, brewer’s yeast 3, gluten powder 3, Soybean meal 8, soybean lecithin powder 2, seaweed powder 2, flour 20, corn gluten powder 3, fish oil 5, sweetfish premix 2.

[0034] Mix various raw materials (except flour, fish oil and sweetfish premix) until the coefficient of variation C.V.<10% of the mixing uniformity, and then pulverize, so that the fineness of the raw materials can reach more than 96%. Pass the 80-mesh standard sieve: add in proportion Flour, sweetfish premix, spray 2kg of fish oil while mixing, mix until the coefficient of variation of mixing uniformity C.V. 98°C, the conditioning time is 2.5-3.0 minutes, optimize and adjust the single-screw extrusion extruder, the first section of the screw at the di...

Abstract

The invention relates to environment-friendly highly-efficient sweet fish compound feed and a processing process thereof, wherein the feed comprises the following raw materials by weight percentage: 5 to 10 percent of white fishmeal, 38 to 42 percent of imported red fishmeal, 3 to 5 percent of shrimp bran, 2 percent of visceral meal, 3 percent of beer yeast, 2 to 4 percent of glutelin meal, 5 to 8 percent of soybean meal, 2 percent of soybean lecithin, 2 percent of seaweed meal, 18 to 20 percent of flour, 2 to 4 percent of maize protein meal, 3 to 5 percent of fish oil and 2 percent of sweet fish premix. Through the selection of swelling process parameters, the processed sweet fish compound feed meets the habit of counterflow ingestion of the sweet fish, improves the stability of the feed in water, meets the nutritional requirement of the growth of the sweet fish, has high utilization rate of feed digestion, reduces the contents of N and P of egesta and reaches the requirement of environmental protection.

Description

Technical field: [0001] The invention belongs to the field of aquatic feed, and in particular relates to an environment-friendly and high-efficiency sweetfish compound feed and a processing technology thereof. Background technique: [0002] Sweetfish is deeply loved by consumers in Japan and Taiwan because of its tender meat, delicious taste and unique fragrance, and has a high economic value (40-50 yuan / kg). In recent years, some areas such as Fujian, Zhejiang and Hebei have set off a wave of aquaculture. According to incomplete statistics, only Fujian and Zhejiang produce more than 6,000 tons of sweetfish each year. The bait coefficient of the existing sweetfish compound feed is Between 1.7-2.0. Because sweetfish has a countercurrent habit and is very active, the sweetfish compound feed requires good water stability. Traditionally processed sweetfish compound feed adopts hard pellets or extruded pellets. The manufacturing process does not pay attention to the research on ...
